A finish equipment operator is a construction equipment operator who specializes in controlling the machines that are used in the final stages of construction products. They work in coordination with a supervisor and a crew of construction workers; when running the machinery, they often communicate via radio or hand signals.
A mill finish is typically the finish a material has as it exits the mill where it is processed. Most metals, such as aluminum, are polished after they leave the mill. This leaves the materials bright and shiny and removes any residue that might be present. A mill finish, however, will often be dull, grainy and without a certain luster. This is often referred to as an unfinished appearance. Any aluminum with this type of finish will contain a slight amount of oxidation. This is a trait of all extruded or rolled aluminum. Steel will also contain a slight oxidation as it exits the rolling mill and typically undergoes a chemical wash to eliminate such an undesirable finish.
